I have a 12 mil clear solar cover and also a light blue 8 mil.
I have been keeping the clear one on during the day and then when the sun goes down I put the light blue one on top of the clear one. My theory is that by putting the second one on I am trapping more heat inside the pool. My water is barely 80 and I like it almost 90, so the quicker the better for getting it warmed up.
1. Does anyone know if putting on the second cover at night is a good plan?
2. If I were to keep both covers on during sunlight hours, would I get a warmer pool faster? Or would the the top cover somehow magnify the heat on the bottom cover and ruin the bottom cover and/or prevent the pool from getting as warm as it would with only one solar cover? Or none of the above?
Thanks for any input.
